GAS-CAPSULE.

SPECIFICATION forming part of Letters Patent No. 696,983, dated April 8,1 902.

Application filed February 8, 1901. $erial No. 6,512. (No model.)

To ctZZ whom it warty concern:

Beitknown that I, GEORGE A. LOGAN,a citi zen of the United States,residing at Chicago, county of Cook, State of Illinois, have invented acertain new and useful Improvement in Gas'Capsulesmf which the followingis a specification.

My invention relates to a form of metallic capsule capable of containingcompressed gas and adapted for use in charging or aerating the fluidcontents of a bottle or other receptacle.

The objects of my invention are to provide a simple and inexpensivecapsule which can be readily applied to the bottle, and particularly toprovide a capsule which can be readily refilled.

To the foregoing and other useful ends I provide the capsule withthreaded and poly onal portions, whereby the capsule can be screwed intoa threaded socket in the bottle-head, so as to puncture the capsule andpermit the gas to escape into the bottle, and, furthermore, I providethe capsule with a removable puncturable seal, whereby the capsule canbe refilled and used again. The construction and manner of using myimproved capsule will, however, hereinafter more fully appear.

In the accompanying drawings, Figure 1 is a side elevation of agas-capsule involving the principles of my invention. Fig. 2 is avertical section on line a: a; in Fig. 1. Figs. 3 and 4. arerespectively a perspective and a section of the seal for closing theopening in the end of the capsule. Fig. 5 is a side elevation of amodified form of capsule. Fig. 6 is a section on line y y in Fig. 5.Fig. 7 is a plan, and Fig. 8 a section, of the seal used in saidmodified form of capsule. Fig. 9 is a plan of the lower end of thecapsule shown in Fig. 5, the opening being unsealed.

As illustrated by Figs. 1, 2, 3, and 4, the capsule A is preferablyoblong and provided with threaded and polygonal portions a and a. Thusformed the capsule'can be screwed into a threaded socket in thebottle-head, the polygonal portion permitting the application of awrench. In this way the capsule can be applied and screwed down untilits end is pierced by the puncturing point or needle. As a simple andeffective arrangement for sealing the capsule the plates B and B areprovided, the former being seated against a shoulder a The plate Bis-threaded and screwed into the capsule and holds the plate B in place.Plate B is provided with a projection b and an opening 1). Plate B isprovided with an opening 12 The gas is forced into the capsule throughthese openings, and the capsule is then sealed by driving or forc ingthe seal C into the opening 12 The said seal is preferably in the formof a metal plug, as shown in Figs. 3 and 4. When driven into thecapsule, the prongs or legs 0 of the plug are deflected outwardly by theprojection b and are thereby clenched on the under side of plate B, theplate B in this way providing a sort of abutment or deflecting-surfacefor spreading or expanding the inner end of the plug. preferably formedwith a head a and an opening a". As a result of such formation the plughas a diaphragm or thin portion 0 which can be readily punctured andwhich is pierced by the puncturing point or needle of the bottle-head. Arubber washer c is preferably interposed between the plate B and thehead of the sealing-plug. Thus constructed the capsule is adapted tocontain gas under pressure and to be employed The outer end of the plugis,

in charging or aerating the liquid contents; 1

of a bottle, theoapsule, as previously stated,

being screwed down until the seal is pierced by the puncturing point orneedle. After the capsule has been used the punctured seal can beremoved, the capsule recharged, and a new seal inserted. In this way thecapsules are refillable and can be used any number of times.

The modified form of capsule shown is pro vided-with an end plate D,having an open ing d, formed with notches d. The seal E is formed with ahead (2, a couple of lugs e, and also with a thin or puncturablediaphragm 6 Thus formed the seal can be inserted through the opening cland turned to bring the lugs out of register with the notches d, therebylocking the seal in place. A rubber washer 6 can be arranged between theplate D and the head e of the seal. As in the previous case the seal Ewhen punctured can be removed, so as to permit the, capsule to berefilled. In either case, however, the seal may be regarded as a plughaving laterallypro'jecting portions which prevent the pressure fromforcing it out of the opening and having ahead limiting itsinsertion insaid opening.

It is obvious that my invention is capable of further modification. Ido' not, therefore, limit myself to the construct-ions shown anddescribed. Prior to my invention the capsules in use could not berefilled, and no practical or satisfactory way of overcoming thisdifficulty had been suggested. I claim, therefore, to be the first toprovide a practical and inexpensive refillable gas-capsule for use incharging or aerating beverages in bottles.

What I claim as my invention is 1. A gas-capsule adapted for use incharging or aerating beverages in bottles or other receptacles, saidcapsule being made of metal and provided with an opening, and aremovable and puncturable metal sealing-plug inserted and removablysecured within said opening, substantially as described.

2. A gas-capsule adapted for use in charging or aerating beverages inbottles or other receptacles, said capsule being made of metal andprovided with an opening, and a removable metal sealing-plug insertedand removably secured within said opening, said plug being provided witha puncturable diaphragm, substantially as described.

3. A gas-capsule adapted for use in charging or aerating beverages inbottles or other receptacles, said capsule being made of metal andhaving a plate or disk seeu red in its open end, said plate or diskbeing provided with an opening or aperture, and a removable metal sealinserted in said opening, substantially as described.

4. A gas-capsule adapted'for use in charging or aerating beverages inbottles or other receptacles, said capsule being made of metal andhaving a plate or disk secured in its open end, said plate or disk beingprovided with an opening or aperture through which the gas isforced intothe capsule, and a metal sealingplug inserted in said opening, said plugbeingprovided with a head limiting its insertionin said opening, and theplug being provided with a bore or passage which is obstructed or closedby a diaphragm or wall, said diaphragm or wall being adapted andarranged in position to be engaged by a projection on the device towhich the capsule is applied, and the plug being readily removable afterthe gas has been liberated from the capsule, whereby the latter can berefilled and used again, substantially as described.

5. A metallic capsule adapted to contain gas or fluid under pressure andprovided with an opening, and a metallic sealing-plug inserted in saidopening and provided with a longitudinal bore or passage, said bore orpassage being obstructed or closed by a diaphragm or wall adapted to beengaged by a point or projection on the deviceto which the capsule is tobe applied, so as to open the passage through the plug and thereby allowthe gas to escape from the capsule, and said plug being readilyremovable after the gas has been liberated from the capsule, whereby thelatter can be refilled and used again, substantially as described.

6. A gas-capsule provided with an opening, a metal plug inserted in saidopening and having its inner end expanded or clenched to prevent thepressure of the gas from forcing it out, the said plug being formed witha puncturable diaphragm and being readily removable, so as to permit thecapsule to be refilled and used again, substantially as described.

7. A gas-capsule formed with screw-threaded and polygonal portions andwith a puncturable end and adapted for use in charging 'or aeratingbeverages in bottles, substantially as and for the purpose set forth.

8. A gas-capsule adapted for use in charging or aerating beverages inbottles and having its opening sealed by a removable metalplughavingahead limitingitsinsertion therein and expanded or clenched atits inner end to an extent to properly seal the said opening but not toan extent to prevent the ready withdrawal of the plug for the purpose ofpermitt-ing a refilling of the capsule.

9'. A gas-capsule adapted for use in charging or aerating beverages inbottles and having its opening sealed by a removable plug formed with ahead limiting its insertion in said opening and withlaterally-projecting portions which prevent the pressure from forcingthe plug out of place, substantially as described.

10. A gas-capsule adapted for use in charging or aerating beverages inbottles and constructed with a suitable opening, an abutment ordeflecting-surface arranged at the inner end of said opening, asealing-plug having a headed outer end and a bifurcated inner end, saidplug beinginserted in said opening and having its said inner end spreador deflected laterally by said abutment or deflecting-surface arrangedat the inner end of said opening, substantially as described.

In witness whereof I hereunto subscribe my name this 15th day ofJanuary, A. D. 1901.

GEORGE A. LOGAN.
